To enter the
Programming Mode
, press the <PGM + UP > keys simultaneously for at least 3 seconds.
Programming Mode allows the user to adjust the following parameters:
Set Units - The display shows the position value in either Millimeters or Inches.
For Millimeters press the <UP> key, for Inches, press the <DOWN> key. The
default value is Inches. Press <PGM> to continue to the next parameter.
Adjust Update rate - This menu allows the update rate to be set (Sampling
Rate) to either 1mSec or 2mSec. For a 1mSec update rate, press the <DOWN>
key. For a 2mSec update rate, press the <UP> key. The default value is
1mSecs. Press <PGM> to continue to the next parameter.
Adjust Gradient - Enter the gradient of the transducer. The gradient value is
found on the Balluff transducer label in “µs/in” (e.g. grad=8.8843µs/in). Initially
the gradient value is set to 9.0000 µs/in with the last digit blinking. Press the
<UP> key to increment this value to the desired setting. Press <SEL> to move
the cursor to the next digit. Press the <UP> and <DOWN> keys to adjust each
digit. Continue this process until all of the digits are set according to the gradient
value marked on the label. Press
<PGM> to continue to the next parameter.

4. Adjust Nominal Stroke - This menu allows the operator to enter the Nominal
Stoke length of the transducer. This will also adjust the NULL and GAIN values
to approximate settings. Exact setting of the NULL and GAIN values will be set
during the
Online Adjust Mode programming. Initially the value is set to 060.0
in, with the cursor blinking in the least significant number. Adjust this value ac-
cordingly, using the
<UP> and <DOWN> keys. Press the <SEL> key to ad-
vance to the next significant number. Follow this process until the value is cor-
rectly entered. Press
<PGM> to continue to the next parameter. Note - When
replacing an existing position transducer, set the nominal stroke to the same
value as that of the transducer being replaced.
5. Set PWM State - This will allow the Pulse Width Modulated output signal to be
either Active high or Active low. For Active high, press the <UP> key. For Ac-
tive low, press the <DOWN> key. The default state is Active low . Press <PGM>
to continue to the next parameter. Note - This step is not needed if only the
analog output is being used .
6. Adjust Number of Recirculations - The number of recirculations of the PWM
output signal can be set between 1 and 16, default is 01. Use the <UP> or
<DOWN> key to adjust the number to the desired value. Press <PGM> to con-
tinue to the next parameter. Note - This step is not needed if only the analog
output is being used.
7. Set Analog State - This allows the user to program the slope of the analog out-
put voltage. Press the <UP> key for Output Rising (-10 to +10Vdc) or press the
<DOWN> key for Output Falling (+10 to -10 Vdc). Rising and falling values are
based on the magnet reading starting at the Null position closest to the electron-
ics. The default setting is Output Rising. Press the
<PGM> key to exit Program-
ming Mode and return to Run Mode.
